Magnet-Spring system fails to vibrate along Y-axis in Solid Mechanics

Please login with a confirmed email address before reporting spam

Hi everyone, I am simulating a haptic motor (vibrator) mechanism. The setup consists of a magnet held between two springs, with a coil positioned at the bottom.

Model Setup:

Physics: Solid Mechanics. Boundary Conditions: Fixed Constraints are applied to the ends of the springs where they connect to the frame. Loading: I applied a Y-axis force to the magnet and coil to simplify the electromagnetic interaction.

The Issue:

Despite the force applied, the magnet does not show any vibration or displacement along the Y-axis in the results.

My Questions:

I have two specific concerns: Constraint/Boundary Conditions: Is the "Fixed Constraint" at the spring ends sufficient? Spring Properties: Aside from assigning a Linear Elastic Material, do I need to define additional settings for 3D springs to behave elastically under dynamic loads?

Looks to me as your Study is an Eigenmode analysis, not a forced analysis.
